Slack stock closed at a fresh all-time high on Monday as traders continued to buy ahead of cloud kingpin Salesforceβs rumored acquisition.
Wind of the deal has now boosted Slackβs share price more than 45% in just three days of trade.
Slack stock even set a new record intraday high of $43.69 early Tuesday morning; in the green over 90% year-to-date, but only up roughly 12% since its IPO in June 2019.
Its previous intraday and closing records were $42 (June 20, 2019) and $40.70 (November 25, 2020).

Thatβs far behind benchmark indices like the S&P 500 and the NASDAQ 100, which have returned 22% and 59% since Slackβs initial New York Stock Exchange listing.
But whatβs been a stellar year for βstay-at-homeβ tech stocks like Zoom and Amazon hasnβt converted quite so well for workplace comms darling Slack.

In September, the companyβs stock fell up to 20% after posting earnings that showed quarterly revenues growing 50% year-on-year β which sounds great but pales in comparison to Zoomβs revenue, which reportedly jumped 355% throughout the pandemic.
On the other hand, traders pumped Salesforce stock nearly 30% after it posted healthy revenue growth in August. However, the companyβs share price has fallen a few points since the Slack rumors began.
The market waits for more details on Salesforceβs Slack buyout
Thereβs currently no word on how much Salesforce is prepared to pay for Slack. CNBC cited sources familiar with the matter who said the deal could value Slack at a premium, and might be made half in cash and half in stock.
Slackβs market value is now a touch under $25 billion. If Salesforce is willing to pay more, it could push the companyβs stock price higher.

But, the opposite could occur if traders have already βpriced inβ Salesforceβs potential valuation, considering its share price has already risen 45% in the past few days.
Analysts say Salesforceβs acquisition of Slack would help the San Francisco SaaS-lord reimagine itself as a hip, young, and relevant brand for tech-savvy workplaces.
More details are expected to drop after Tuesdayβs trading session has ended.
